Folio Reader by ThoughtBubble

Folio is a fast, private home for the books you own. Open DRM-free EPUBs, PDFs, and comics on a calm page that gets out of the way, and keep your whole library on your own devices. THE READING ROOM • Six themes: Light, Warm Sepia, Parchment, Slate, Dark, and OLED Black, or follow the system. • Publisher, Serif, Sans, Rounded, or Mono type with adjustable size, page width, and line spacing. • Turn pages or read in one continuous scroll. • PDFs add a reflowed Text mode for small screens. • Folio remembers your place by the passage itself, so it holds steady when the layout changes. HIGHLIGHTS, NOTES, AND SEARCH • Highlight passages, add notes, and set bookmarks. • Search inside a book and jump straight to the line. • See progress, highlights, and notes for every book at a glance. YOUR LIBRARY • Import from Files, share from Safari or other apps, or download from a catalog. • Folio reads covers and details and shelves every book automatically. • Continue Reading and recent books wait on Home. • Browse by cover or list, filter by format, and search by title, author, or series. • Built for libraries of ten thousand books and more. OPDS CATALOGS • Connect Calibre, Komga, Standard Ebooks, Project Gutenberg, or any OPDS 1 or OPDS 2 feed. • Browse by cover, search, and download straight into your library. • Password-protected catalogs keep their credentials in your Keychain.

Your library, reading positions, highlights, and notes stay in the app on your devices. Optional sync uses the private CloudKit database in your own iCloud account and is off until you turn it on. Folio does not remove DRM and only opens books without copy protection. SUPPORT Visit folio.thoughtbubble.dev/help or email support@thoughtbubble.dev.
